County Prestress & Precast’s ArchCast® Precast Bridge System is a modular, precast concrete solution designed for accelerated bridge construction and long-term durability. The system delivers visually refined crossings for vehicular, pedestrian, and wildlife applications while significantly reducing on-site construction time and overall project complexity.
ArchCast precast concrete components are manufactured in a controlled facility, ensuring consistent quality that meets AASHTO and ASTM standards, as well as DOT material requirements. By minimizing field-forming, curing, and weather-related delays, the system enables faster installations and shorter road closures than cast-in-place methods.
The fully integrated system—comprised of arched spans, wing walls, head walls, and retaining walls—simplifies construction sequencing and reduces staging requirements, making it well-suited for projects with tight access or environmental constraints.
ArchCast bridges support clear spans from 12′ to 60′, with ArchCast Twin Leaf units available for spans beyond 60′. The natural arch geometry provides an efficient structural section that often requires less reinforcement than flat-top designs, improving both material efficiency and structural performance.
This modular approach allows crossings to be designed for specific site conditions while maintaining predictable performance and simplified installation sequencing.
Manufactured using high-strength precast concrete, ArchCast components are built to resist corrosion, weathering, and long-term environmental exposure. With a service life of up to 100 years, the system reduces maintenance demands and lowers life-cycle costs compared to steel or cast-in-place alternatives.
The durability of precast construction ensures reliable performance across a wide range of infrastructure applications, from high-traffic roadways to environmentally sensitive crossings.
By eliminating the need for extensive forming, curing time, and large construction crews, the ArchCast system reduces overall project duration and labor demands. The efficient arch geometry also requires less concrete and reinforcement than many traditional cast-in-place bridge designs, helping reduce material usage while improving construction efficiency. Precast retaining walls use an earth-anchor design that eliminates the need for tiebacks, preserving the surrounding terrain and improving buildability.
Compared to traditional bridge systems, ArchCast offers a more economical solution with lower long-term maintenance requirements and improved installation efficiency.
ArchCast bridges combine structural performance with visual adaptability. Optional formliner finishes applied to headwalls and wingwalls can replicate stone, brick, or custom textures, allowing the structure to blend seamlessly into surrounding landscapes.
These aesthetic enhancements can be achieved without altering structural design requirements, providing greater flexibility while maintaining construction efficiency.
The open-bottom arch design allows natural waterways and streambeds to remain largely undisturbed, supporting aquatic ecosystems and reducing environmental impact. This makes ArchCast an effective solution for projects requiring regulatory compliance or environmental sensitivity. The reduced footprint, fast installation, and minimized site disruption contribute to more sustainable infrastructure development.
ArchCast Precast Bridge System is well-suited for:
· Highway and road crossings
· Pedestrian and bicycle bridges
· Wildlife crossings
· Drainage and waterway structures
· Tunnels for pedestrians, wildlife, or golf carts
· Underground detention systems
Custom sizes, rise configurations, and integrated openings for utilities or drainage can be incorporated during manufacturing, allowing the system to adapt to a wide range of project conditions.
ArchCast Precast Bridge System delivers accelerated construction, structural efficiency, and long-term durability in a fully integrated precast solution. With reduced installation time, lower life-cycle costs, and adaptable design capabilities, it provides a dependable alternative to traditional bridge construction methods.
